Disclosed is a light emitting module capable of representing improved heat radiation and improved light collection. Even though the public key is reduced, in some embodiments of the invention the ensemble of cryptograms produced is identical to the ensemble of cryptograms produced by the original system for a given Goppa code, and the same private key. The metallic portion includes two lead-out terminals electrically coupled to the capacitor element, and these two lead-out terminals are electrically isolated from each other by the resin portion. The inner circumferential member is arranged on the inner circumferential side of the outer circumferential member. The optic combining portion combines modulated light beams emitted from the optic modulator.
